Abstract. This article presents main markers of the research line named political communication science. The analysis of the foreign literature has allowed the author not only to establish the stages and the current status of the mentioned research field but to demonstrate the current level of knowledge of political communication. This article reveals the tight interrelation between genesis of political communication science and the theoretical understanding of state administration, efficiency and legitimacy of administrative authority decisions. The research area of the western political system was shown restricted up to the solution of particular issues, whereby the author considers the problem how to move the political сcommunication science to a new level by means of expansion of research interest in media sphere, political advertizing, PR and even awareness campaign.The modern political science considers the term of political сcommunication in different aspects.
